A torque limiting coupling defines a longitudinal axis (17) and has a coupling hub (8) with circumferentially distributed through holes. Transfer elements are adjustably held in the holes. A coupling sleeve (6) has first recesses corresponding to the through holes. A switching disk (9) is arranged relative to the coupling hub (8) between a torque transmitting position and a freewheeling position. The switching disk (9) is urged towards the torque transmitting position. This urges the transfer elements in the direction towards the coupling hub (8). The transfer elements engage, for torque transmission, in recesses of the coupling sleeve (6). Coupling sleeve (6), when a predetermined nominal torque is exceeded, is transferable from the torque transmitting position to the freewheeling position. Second recesses, corresponding to the through holes, receive the transfer elements in the freewheeling position. A locking pawl (14), in a retaining position, interacts at least with one switching face (11) of the switching disk (9). The switching disk (9) is transferable from the torque transmitting position into the freewheeling position. In the retaining position, the locking pawl interacts with a first retaining face (19) of the coupling hub (8) so that the torque limiting coupling (1) is retained against rotation.
