Abstract
A variable-diameter power-transmission device comprises a rotatable member and a plurality of arms attached at their inner ends to the rotatable member and extending outwardly in a radial direction, the arms being curved at their outer ends in a circumferential direction to provide a generally cylindrical coupling surface for coupling to another device, the arms being flexible, permitting them to flex with respect to the rotatable member to change the radial distance of the outer end of the arms from their inner ends, and thereby to change the effective diameter of the coupling surface.
