Abstract: Embodiments of the present invention relate to a flexible coupling for connecting a driving rotatable shaft to a driven rotatable shaft, where the flexible coupling allows greater relative misalignment and/or offset of the shafts compared to known couplings. The coupling may further enable control of torsional and axial stiffness.

Abstract: A flexible coupling for coupling together a pair of axially misaligned shafts of which the respective ends of the shafts retainably fit within a hub within the interior of which the longitudinal axes of the shafts meet at a common point. A plurality of arms extend radially outwardly along the hub and a portion of the hub adjacent each and extend toward each other into the interior of the hub into contact with a bearing contained within the hub of the common point, whereby ends of each respective shaft and hub retaining portion are movable relative to one another.
