Abstract
An improved Oldham coupling ring is relatively easy to manufacture. Opposed circular arc portions are connected by angled portions to opposed flat portions. The circular arc portions are centered on a common center. As such, the invention is relatively easy to manufacture when compared to prior art systems.
