Abstract
A flexible shaft coupling comprises a rigid hub coupling part and a rigid ring coupling part which surrounds the hub part concentrically, the two parts being connected together by two similar symmetrically disposed resilient rings which bulge outwards away from each other to form a cavity between them. In order to vary the resilience of the coupling to suit requirements and avoid torsional oscillations, the outwardly bulging parts of the resilient rings are supported against each other by a resiliently deformable annular element which extends axially across, but does not fill, the cavity.
