A apparatus in the form of a torsional propulsion device functioning as an engine (10) for delivery of sustained mechanical power over an extended duration with only intermittent energy input. The engine (10) comprises an input shaft (11), an output shaft (13) and a drive mechanism (40) therebetween. The drive mechanism (40) comprises a drive gear (45), an input mechanism (71), and a spring mechanism (73) operably connected to the drive gear 45. The spring mechanism (73) is adapted to be loaded by the input mechanism (71) during the loading event. The loaded spring mechanism (73) is adapted to rotate the drive gear (45) in a driving direction during a driving event, the driving event being of a duration exceeding that of the loading event. The duration of the driving event is significantly greater than the duration of the loading event such that the drive mechanism (40) can deliver output energy for an extended duration as compared to the duration of energy input. Typically, the duration of the driving event is of at least an order of magnitude greater than the duration of the loading event.
