A coupling, used in drivelines or for driving agricultural implements, has a first coupling element () and a second coupling element (). An actuating element () is axially displaceable relative to the first coupling element () between a switched-on position and a switched-off position. A power drive () actively displaces the actuating element (). The power drive () loads the actuating element () in the switched-on position against an abutment mechanism (). A first spring (), in the switched-on position of the actuating element (), loads the friction assembly (). This enables the friction assembly () to assume the torque transmitting position.

Coupling

A torque limiting coupling has a first coupling hub () with first driving members (), and a second coupling hub () with second driving members (). The hubs () are jointly received in a coupling sleeve () and are rotatable independently of one another. When a set torque is exceeded while the first coupling hub () is driven in one of two driving directions of rotation Nor N, the second coupling hub () is subjected to a force which ensures that, in the driving direction of rotation N, the driving members () of the first coupling hub () are transferred into the disconnected position and that, in the driving direction of rotation N, the second driving members () of the second coupling hub () are transferred into the disconnected position.
