A torque limiting device comprises rotationally mounted input and output shafts, an intermediate drive element rotationally coupled to the input shaft and a plurality of jammer elements mounted between the intermediate drive element and the output shaft. A spring mechanism is connected between the input shaft and the intermediate drive element for aligning the intermediate drive element and the input shaft in a driving configuration in which rotation of the input shaft at a torque below a predetermined threshold is transmitted to the output shaft via the jammer element, but in which torque above the predetermined threshold moves the input shaft rotationally relative to the intermediate drive element against the force of the spring mechanism so as to disengage that jammer elements from driving engagement with the output shaft.

The invention relates to an overunning clutch, comprising a torque-introducing clutch element, a torque-receiving clutch element and switching element, which is forced from an engagement position into a freewheeling position or from a freewheeling position into an engagement position in dependence on the direction of a sufficient change in the rotational angle position between the torque-introducing clutch element and the torque-receiving clutch element by means of an actuating force applied to the switching element by an actuator. According to the invention, the actuating force is a friction-induced actuating force, which is induced by means of a friction-force pairing between the actuator and a component of the overrunning clutch that is in frictional contact with the actuator and the actuator forms an interlockingly acting actuating stop, by means of which the actuating force acts on the switching element.

A torque limiter assembly is disclosed comprising a housing having at least one first engagement member, an input shaft that is rotatable relative to the housing and having at least one second engagement member; and an electromagnet. The electromagnet 10 is arranged and configured such that when activated it generates a magnetic field that moves the at least one first engagement member relative to the at least one second engagement member, such that the first and second engagement members engage each other and stop or inhibit rotation of the input shaft relative to the housing.
