Patent ID: 8529359

Claim:
A shaft coupling system comprising: a first shaft engagement member that can be connected to and rotate in unison with a first shaft; a second shaft engagement member that is located adjacent the first shaft engagement member and that can be connected to and rotate in unison with a second shaft; and a plurality of links, wherein each link has a first end that is connected to the first shaft engagement member and a second end that is connected to the second shaft engagement member so that torque can be transmitted between the first and second shaft engagement members through the links, wherein at least one of the links extends angularly between the first and second shaft engagement members and is resiliently bendable with respect to at least one of the first and second shaft engagement members and includes a curved segment that extends along an arcuate path that curves continuously between the first and second ends of the link so as to evenly distribute stress and avoid stress concentrations within the link.
