A Schmidt coupling is a mechanical device used to connect two shafts and accommodate substantial radial displacement between them. It consists of a configuration of links and discs, typically three discs that rotate together and are interconnected by three or more links between each pair of discs. The Schmidt coupling is capable of adapting to significant variations in radial displacement, even while operating under a load. Some designs of these couplings can facilitate radial displacement exceeding twice the radius of the discs.
