ABSTRACT:
Addressed are couplings for transferring rotational motion from one shaft to another. The couplings may include flexible components and may be designed to accommodate angular, axial, and parallel misalignments. Included as components of the couplings may be hub portions, each having dowel pins and clearance holes, and a center member positioned intermediate the hub portions.
