Abstract: An apparatus for securing an insert in a hole, the insert having an axis, a section comprising a thread disposed around the axis and a section comprising a plurality of splines, and the hole having a section comprising a corresponding thread and a section comprising a plurality of grooves corresponding to said splines, the apparatus comprising a driver arranged to rotate the insert, a torque measurement device arranged to measure the driving torque applied by the driver, and a controller arranged to cause the driver to drive the insert into the hole until the splines are level in the axial direction with the grooves by rotating the insert in a first direction, and align the splines with the grooves by causing the driver to further rotate the threaded insert whilst measuring the driving torque using the torque measuring device, and stopping the further rotation based on the measured driving torque.
