Actuating system comprising an actuator with a torque-transmission element for a movable element, in particular a swing-action panel in a motor vehicle, the movable element being mounted pivotably in a basic hinge element. The actuating system has a torque support arranged functionally between the basic hinge element and the actuator, at least one key profile being made in the torque support, so that it is possible to bring about axial plug-connection assembly with the basic hinge element.

1. An actuating system for a movable element, said actuating system comprising:a basic hinge element comprising a mounting and a movable element which is pivotably mounted with respect to said mounting, said mounting having a mating profile;a torque transmission element which is received in said basic hinge element and fixed against rotation with respect to said movable element for pivoting said movable element with respect to said mounting;a housing;an actuator which is fixed in said housing for transmitting torque to said torque transmission element; anda torque support which is fixed against rotation with respect to said housing and with respect to said mounting of said basic hinge element, said torque support having a key profile which can be plugged into said mating profile of said mounting so that the torque support cannot rotate with respect to said mounting. 2. An actuating system as in claim 1 wherein said torque support comprises a hollow member which receives said torque transmission element through said hollow member. 3. An actuating system as in claim 1 wherein said mounting consists of a retaining plate having a through passage which forms said mating profile. 4. An actuating system as in claim 1 wherein said housing has a mating profile, said key profile on said torque support engaging in said mating profile of said housing so that the torque support cannot rotate with respect to said housing. 5. An actuating system as in claim 1 wherein said torque transmission element comprises a key profile which engages in a mating profile of said movable element. 6. An actuating system as in claim 1 wherein said housing comprises a framework in which a bearing having a mating profile is journaled, said torque transmission element comprising a key profile which can be plugged into said mating profile of said bearing to fix said torque transmission element against rotation with respect to said bearing, said bearing being arranged to transmit torque from said actuator. 7. An actuating system as in claim 6 further comprising a first gearwheel driven by said actuator and a second gearwheel fixed on said bearing, said first gearwheel being in driving engagement with said second gearwheel.
