A torque limiting device (18) comprises a rotationally mounted input shaft (20); a rotationally mounted output shaft (22), an intermediate drive element (24) rotationally coupled to the input shaft (20) and a plurality of jammer elements (60) mounted between the intermediate drive element (24) and the output shaft (22). A spring mechanism (84) is connected between the input shaft (20) and the intermediate drive element (24) for aligning the intermediate drive element (24) and the input shaft (20) in a driving configuration in which rotation of the input shaft (20) at a torque below a predetermined threshold is transmitted to the output shaft (24) via the jammer elements (60), but in which torque above the predetermined threshold moves the input shaft (20) rotationally relative to the intermediate drive element (24) against the force of the spring mechanism (84) so as to disengage that jammer elements (60) from driving engagement with the output shaft (24).
