Abstract: A torque limiting coupling rotatably arranged around a longitudinal axis A has a coupling hub (2, 102, 202), drivers (6, 106), a coupling sleeve (3, 103, 203) and a switching disk (4, 104, 204). The switching disk (4, 104, 204) is rotatably arranged between a switched-on position and an idling position relative to the coupling hub (2, 102, 202). The drivers (6, 106) engage the coupling sleeve first recesses (7, 107,207) in the switched-on position. The drivers (6, 106) engage the switching disk second recesses (8, 108, 208) in the idling position. A first spring mechanism (25, 125, 225) urges the switching disk (4, 104, 204) in the direction towards the switched-on position. A second spring mechanism (12, 112, 212) acts axially on the switching disk (4, 104, 204) and urges the drivers (6, 106) against the coupling sleeve (3, 103, 203).
