In order to increase an automatic connecting speed at a torque limiting coupling, a torque limiting coupling (1) with a longitudinal axis has a coupling hub (5) with circumferentially distributed apertures. Driving elements (8) are adjustably held in the apertures and extend parallel to the longitudinal axis. A coupling sleeve has first recesses (23) corresponding to the apertures. A switching disc (14) is rotatably arranged between a connected position, where the driving elements (8) engage the first recesses (23) for torque transmitting purposes, and a freewheeling position, relative to the coupling hub. The switching disc (14), if a predetermined nominal torque is exceeded, can be transferred by a rolling movement of the driving elements (8) from the connected position into the freewheeling position. The switching disc (14) has second recesses (34) that correspond to the apertures and engage the driving elements (8) in the freewheeling position. A first spring mechanism loads the switching disc (14) in the circumferential direction towards the switching position. A second spring mechanism axially loads the switching disc (14). The driving elements (8) move indirectly towards the coupling hub. Circumferential play (28) is formed between the driving elements (8) and the first recesses (23) in the connected position.
