An Oldham coupling has three discs, one coupled to the , one coupled to the output, and a middle disc that is joined to the first two by tongue and groove. The tongue and groove on one side is perpendicular to the tongue and groove on the other. The middle disc rotates around its center at the same speed as the and output shafts. Its center traces a circular orbit, twice per rotation, around the midpoint between and output shafts. Often springs are used to reduce backlash of the mechanism. An advantage to this type of coupling, as compared to two universal joints, is its compact size. The coupler is named for John Oldham who invented it in Ireland, in ***0, to solve a paddle placement problem in a paddle steamer design.
