<P> In mechanical engineering , a key is a machine element used to connect a rotating machine element to a shaft . The key prevents relative rotation between the two parts and may enable torque transmission . For a key to function , the shaft and rotating machine element must have a keyway and a keyseat , which is a slot and pocket in which the key fits . The whole system is called a keyed joint . A keyed joint may allow relative axial movement between the parts . </P>
