A coupling comprising two hubs (1) elastically joined to a hollow shaft (2), which surrounds the hubs, by six elastically resilient links (3) which are bolted alternatingly in an hexagonal pattern to a hub flange (10) and a shaft flange (20) at the ends of the coupling. This permits parallel and angular misalignments according to the cardanic principle while torque is being transmitted. Because the flanges lie in the same transverse plane, the coupling is protected against slipping in the event that the resilient link elements should fail. Because the links are externally mounted, they permit optimum cardanic motion. The hubs may be fitted inside the hollow shaft (short configuration) or they may bolted on so as to project beyond the ends of the hollow shaft (long configuration).

An elastic shaft coupling consisting essentially of two identical flanged hubs and a flanged hollow shaft adapted to receive cylindrical parts of said identical hubs with predetermined play, one end of each of the two hubs being linked to the hollow shaft by means of a respective resilient ring element bolted alternatingly to the flange of the hub and the flange of the hollow shaft with bolts parallel to the axis of said shaft, the ring elements comprising individual polygonally arranged resilient links, the flanges having radial stops formed thereon, the hub flanges and hollow shaft flanges projecting radially outwardly in the same transverse plane radially outside the hollow shaft, the hollow shaft being provided with axially extending recesses through which the hub flanges extend, the recesses having axial lengths greater than the axial lengths of the flanges, the hollow shaft being more than twice a hub length, and the elastic ring element bolts being bolted frontally to the coupling.
