A flexible coupling of the gear type is provided with mating teeth that have a substantial radial clearance between the major diameters of the internal and external gear teeth. Provisions for centering the floating member are located at the minor diameters of the respective gear teeth. In this configuration of coupling gear teeth, the lubricating oil is allowed to flow freely through the aforesaid radial clearance, thereby tending to prevent solids, centrifuged out of the lubricant as a result of rotation, from impairing coupling operation.
