According to one aspect of the invention there is disclosed herein a stand head assembly (10). The stand head assembly (10) comprises a coupling (12) to facilitate coupling between an object to be supported and a stand body (14). The coupling (12) has an object face (16) adapted for operative attachment to the object to be supported, and an opposing support face (18) adapted for operative attachment to the stand body (16). The stand head assembly further comprises a drive assembly (20) which is operatively associated with the stand body (14) and adapted for attachment to the coupling (12). The drive assembly (20) includes a drive dog (22) which is operatively adapted to impart pivotal movement to the coupling. A securing assembly (24) is provided which is operatively adapted to secure the coupling to the drive assembly. The coupling (12) includes a drive slot (26) operatively associated with the drive dog (22) of the drive assembly. The drive slot is operatively adapted (i) to receive and hold the drive dog (22) and (ii) to provide a contact surface (28) to be acted upon by the drive dog (22) so as in use to impart pivotal movement to the coupling (12) and the object to which the coupling is mounted. In one embodiment the stand head assembly is incorporated in an engine stand.
