Claim 7:
8. The method as claimed in claim 1, further comprising:
taking a kit comprising a measuring device and an adaptor,
the adaptor being configured to fit onto and/or around an element, the element having a point of interest, and the adaptor comprising an at least part-spherical bearing surface having a center point that, when fitted onto and/or around the element, substantially coincides with the point of interest, and
the measuring device comprising a coupling element that is configured to couple to and bear against the bearing surface of the adaptor such that a measurement point of the measuring device is substantially coincident with the center point of the adaptor and remains so as the coupling element moves over at least a predetermined or working part of the bearing surface;

fitting the adaptor onto and/or around the element;
with the element still on the coordinate positioning machine, coupling the measuring device to the adaptor so that the coupling element of the measuring device bears against the at least part-spherical bearing surface of the adaptor; and
performing a measurement operation such that during the measurement operation the measurement point of the measuring device is coincident with the center point of the adaptor and remains so as the coupling element of the measuring device moves over at least the predetermined or working part of the bearing surface of the adaptor.
