A hybrid power unit 1 of a work machine includes an internal combustion engine 10 and an energy storage device 20 (for example a flywheel). The engine includes a crankshaft 11 for driving a load and the crankshaft is attached to the energy storage device via a torque fuse such as a clutch 40. The energy storage device can be charged by the engine to store energy that may be used to provide, when required, a boost to engine performance. The clutch may engage/disengage the energy storage device from the engine and/or control a clutch pressure. The clutch protects the crankshaft from shock loading and can slip to prevent over·torqueing of the crankshaft. The variable transmission of the engine has a first torque capability, and the clutch has a second torque capability which can be modified to be less than that of the variable transmission.
