A method of coupling a tool to a length of tubular comprises securing the tool in a basket; lowering a tong arrangement having a rotary part and a stationary part, relative to the basket to engage respective locking members of the tong arrangement and the basket, thereby fixing the basket and the tool relative to the stationary part of the tong arrangement; and rotating the length of tubular using the rotary part of the tong arrangement so as to couple the tool to the length of tubular. A torque measuring flange may be associated with the tong arrangement. The torque measuring flange comprises a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.
