A composite shaft with an end fitting mounted on an interface region on at least one end of said shaft, and a preload structure arranged to provide a biasing force to bias the composite shaft against the end fitting; wherein the preload structure is in an interference fit with the composite shaft. The preload structure is applied to the composite shaft in a subsequent operation to the mounting of the end fitting to the shaft.

A frictionally locking shaft/hub clamping connection (1) having at least two cone clamping rings (4, 5) which bear against one another on their cone faces (4a, 5a) and can be pushed onto one another axially by way of clamping elements (6), the radial forces which are produced bringing about a frictionally locking connection between the shaft (2) and the hub (3). The cone faces (4a, 5a) of the clamping rings (4, 5) which bear against one another have a non-round cross section which differs from the circular shape.
