 the coupling bearing point of the coupling device is positioned above the connection level. 
 
     
     
         2 . Mounting device according to  claim 1 , wherein the coupling bearing point of the coupling device is positioned in a region above the rotary feedthrough to the drive housing. 
     
     
         3 . Mounting device according to  claim 1 , wherein the coupling device is provided on the connection plane of the drive housing in a rotationally fixed and/or non-pivotable manner. 
     
     
         4 . Mounting device according to  claim 1 , wherein the coupling device is provided detachably on the fictitious connection plane, or in that the coupling device is provided integrally on the drive housing. 
     
     
         5 . Mounting device according to  claim 1 , wherein the coupling device has two cheeks which are provided detachably on the cover surface, formed at least in sections, of the drive housing or are integrally formed thereon. 
     
     
         6 . Mounting device according to  claim 5 , wherein the two cheeks of the coupling device are connected to one another by at least one connecting plate. 
     
     
         7 . Mounting device according to  claim 1 , wherein the drive housing has at least one flattening between its cover surface, which extends at least in sections, and the end face. 
     
     
         8 . Mounting device according to  claim 7 , wherein the at least one flattening is inclined at an angle of 15° to 75° relative to the cover surface in the direction of the end face. 
     
     
         9 . Mounting device according to  claim 7 , wherein the at least one flattening is shortened by a distance of the axis of the attachment bearing point in the direction of the axis of rotation of the rotary device. 
     
     
         10 . Mounting device according to  claim 1 , wherein at least one connecting plate is provided, which is connected to the flattening or rests against the flattening, and at least one further connecting plate is provided, which is connected to the cover surface. 
     
     
         11 . Mounting device according to  claim 1 , wherein the attachment bearing point is assigned to the flattening or the end face. 
     
     
         12 . Mounting device according to  claim 1 , wherein the attachment bearing point and the coupling bearing point are arranged at an angle (β) to a plane of rotation of the rotary device or parallel to the plane of rotation of the rotary device, which results from two fictitious straight lines, wherein one fictitious straight line extends through the coupling bearing point and the attachment bearing point and the other fictitious straight line lies in the plane of rotation or runs parallel thereto and extends through the attachment bearing point. 
     
     
         13 . Mounting device according to  claim 12 , wherein the fictitious straight lines are arranged at an angle (β) of 15° to 45°, or at an angle (β) of 25° to 35°. 
     
     
         14 . Mounting device according to  claim 1 , wherein a rotary feedthrough is arranged in the drive housing, which rotary feedthrough has a stator which is rotationally fixed on the drive housing and a rotor which is rotatable relative to the stator, is connected to the clutch and is connected to at least one connection, in the clutch. 
     
     
         15 . Mounting device according to  claim 6 , wherein the at least one connecting plate is detachably connected to the rotary device.
