Rotary drive apparatus utilizes a cable extending about and between two rotatable members or elements, and the cable end terminations are secured to one of the elements by means of tension springs anchored within one of the elements. The tension springs provide two functions, one function is a pre-load bias on the cable and the second function is a tension force for withdrawing cable ends into the driven member in case of a break in the cable.
