Described herein is a coupling device, associated parts and a method of use thereof. In one aspect, a coupling device is described comprising a sleeve with an inner surface that encloses at least part of at least one elongated element to be coupled; and at least one deformation means fitted with interference between, and causing local deformation about, at least part of the inner surface of the sleeve and/or an adjacent outer surface of the at least one elongated element. A deformation means insertion tool, a coupling sleeve, a deformation means, and a method of coupling at least one element are also described. The described coupling device, associated parts and a method of use offer the ability to couple together different elements in a strong and/or ductile manner, coupling being tuneable as needed to suit the preferred application. The coupling described may overcome art issues associated with bulky size of coupling, in particular, radial protrusion. The coupling may also increase the coupling force therefore increase the load that may be managed across the coupling device. Further, the way the parts are assembled may minimise generation of localised points of stress therefore also increasing the load that may be managed across the coupling device.

Coupling device, associated parts and a method of use thereof

A hydraulic control system HCS for controlling a variable ratio transmission of a power generating system. A hydraulic motor/pump unitis operably connected to a superposition gear, and is connected to a hydraulic circuit that comprises an orificeand/or a relief valvethat opens at a predetermined hydraulic pressure. The hydraulic circuit switches between a variable low-speed operating mode and a torque limiting high-speed operating mode. In the torque limiting high-speed operating mode the hydraulic motor/pump unitis driven by the superposition gear and drives hydraulic fluid through the orificeand/or relief valveto provide a passive torque limiting function. In the variable low-speed operating mode the hydraulic motor/pump unitdrives the superposition gear and the hydraulic control system provides a desired rotorspeed by controlling hydraulic fluid flow rate through the hydraulic motor/pump unit
