Abstract
A system to allow a visual determination of the rotational position of a rotatable object relative to a stationary object comprising a body defining front and back surfaces where the body includes at least one aperture having a diameter d1 disposed through the front and back surfaces, where the aperture is bounded by radial slots having a length l and extending outwardly from the aperture so as to define a plurality of fingers which may be independently manipulated so as to enable the body to be biased about a rotatable object inserted through the aperture and means co-operable with the body to allow a visual determination of the rotational position of the rotatable object relative to the stationary object.

A system to allow a visual determination of the rotational position of a rotatable object relative to a stationary object comprising:
- a body defining front and back surfaces where said body includes at least one aperture having a diameter d1 disposed through said front and back surfaces where said aperture is sized to fit about said rotatable object said body including a temperature sensitive coating which changes from a first to a second color when exposed to temperatures beyond a predetermined value;
- said aperture bounded by radial slots having a length l and extending outwardly in from said aperture so as to define a plurality of fingers which may be independently manipulated so as to enable said body to be biased about a rotatable object inserted through said aperture where each of said slots defines substantially parallel sides to said fingers over said length l;
- and
- means co-operable with said body to allow a visual determination of the rotational position of said rotatable object relative to the stationary object.
A device for indicating relative rotational displacement between a fixed first member and a second member, said device comprising:
- a body defining a bore therethrough to accommodate said second member;
- said bore defining a series of slits extending to a second diameter so as to define a series of fingers where said fingers are adapted to deform to accommodate the through passage of said second member where each of said fingers is substantially parallel to each adjacent finger said body further including a temperature sensitive coating which changes from a first to a second color when exposed to temperatures beyond a predetermined value;
- and
- indicating means to indicate the position of the device relative to a reference.
