Reporters obtained the following quote from the background information supplied by the inventors: “Torque transferring devices for connection to the output shaf t of a power tool, such as sockets for tightening of nuts or screws, extensions or adapters, such as quick-change adapters, are well known. For example, a well- known standard type of socket has a square cross sectional recess at its rear en d intended for receiving the square shaped end portion of a power tool output sh aft and an internal cross sectional shape adapted to fit the type of screw joint to be tightened, for instance a hexagonal shape, at its front end. Similarly, a n adapter or extension may comprise the same type of structure for receiving the square shaped end portion of a power tool output shaft but, at its front end, a structure for engaging the rear end of a socket or similar.
