A single piece coupling device for connecting a load component to a rotatable shaft. The device comprises a sleeve having a bore for containing a rotatable shaft, an externally threaded portion and a tapered engagement face on the outer surface of the sleeve. Radial compression relief associated with the tapered engagement face is provided such that when the device is fitted on a shaft, and as the threaded portion engages with a corresponding threaded region on the load component, the tapered engagement face engages the load component and the compression relief enables the sleeve to be radially compressed to grip the shaft.
