A composite shaft assembly includes a core having an outwardly facing surface. At least one structure embedded in a resilient material extends from the outwardly facing surface. The outwardly facing surface defines an outer surface spaced from the outwardly facing surface which is fixable to an inner surface of a composite shaft.

Composite shaft end assembly and composite shaft formed therewith

A flexible coupling is provided to connect a flange on a drive shaft to a flange on a driven shaft. Circumferentially spaced fastening means provide bores through the coupling through which bolts can be passed to connect it alternately to the one and then the other flange. Adjacent fastening means are interconnected by link and washers are positioned at opposite ends of the stack of links at each fastening means. In accordance with the invention the washers are formed with peripheral grooves which will be entered by the plastics material forming the body of the coupling, thus locking the washers against being expelled when bolts are subsequently passed through the bores.
