ABSTRACT A stress relief device for a flexible shaft used to connect a rotary drive to a rotary load, wherein the shaft flexes in response to loads that produce bending stresses during shaft rotation. The shaft has a radial flange, or hub, on at least one end for connecting the respective end to another rad- ial flange on either the rotary drive or the rotary load. In order to relieve the joint between the shaft and the hub from the stress concentration that occurs due to flexure of the shaft while being supported as a cantilever beam, an annular stress relief member is mounted on the shaft inwardly of and tightly secured to the radial flange, or hub. The specially designed stress relief member is tightly positioned around the underlying cylindrical surface portion of the shaft to provide a fixed-end cantilever-type support therefor so that beading stresses occurring due to shaft flexure are more gradually transmitted to and through the stress relief member to avoid stress concentration at the junction of the shaft and the radial flange, or hub.
