Abstract:
1. A single piece coupling device for connecting a load component to a rotatable shaft, said device comprising 1) a sleeve having a bore, said bore includes at least one flat surface wherein the flat surface engages a complimentary surface on the shaft, 2) the sleeve having an outer surface including an externally threaded portion and a tapered engagement face; 3) a radial compression relief means associated with the tapered engagement face, such that when the device is fitted on a rotatable shaft and as the threaded portion engages with a corresponding threaded region on a load component, the tapered engagement face engages the load component and the compression relief means enables the sleeve to be radially compressed to grip the rotatable shaft; 4) an engagement projection within the bore of the sleeve adapted to mate with a complementary recess on a rotatable shaft to be gripped by the device to restrain relative longitudinal displacement between the device and the rotatable shaft when mounted on the rotatable shaft; and 5) wherein said load component is a fan.
