The sleeve includes an elongate axial wall for being positioned in contact with an outward facing surface of the main shaft. The axial wall has a thickness that decreases in a direction from a second upper end to a first lower end, wherein the internal facing surface of the sleeve extends transverse to a longitudinal axis of the sleeve so as to taper inwardly towards the axis in a direction from the first to the second end.
