Abstract: A shaft coupling assembly particularly intended for use with a taper shaft utilizes a tapered inner bore having an internally threaded portion for receipt of a torque applying jacking plug, and one or more impact receiving striking surfaces to facilitate removal of the shaft coupling from a shaft. The contemporaneous application of torque to the coupling through the jacking plug and impact to the coupling through the striking surfaces breaks the coupling loose from the taper shaft, even in situations where there is only limited space in which to deliver impact blows.
