Abstract: A flexible shaft coupling including coupling flanges and a stack of sprinlastic membranes mounted at an axial distance from the two coupling flanges. The stack of membranes is mounted on sleeves which are arranged on tightening bolts mounted alternatingly on a circle on one or the other of the coupling flanges. Spacer washers are arranged next to the stack of membranes. Each sleeve is a hardened cutting sleeve provided with a cutting edge. The cutting sleeve is forced into the respective bore of the stack of membranes and at least a portion of the cutting sleeve is forced into the corresponding bore of the coupling flange. The cutting sleeve has an outer diameter which is greater than the maximum diameter of the respective bore of the stack of membranes and of the corresponding bore in the coupling flange.
