# Rotatable, self-aligning lobe coupling

## Abstract

A rotatable coupling having a male member (2) and a female member (4) each rotatable about central axes α and β. The male member has lobes (16) and the female member cavities (50) for mutual engagement. The male lobes terminate in wedge-shaped portions (18), the edges of which lie in a common plane. The female terminates in a flat bottom surface (40).
