An exhaust gas temperature (EGT) sensor 520 comprising an anti-rotation element 510, the anti-rotation element 510 comprising a C-shaped fixture portion 517 constrained to a body of the EGT sensor 520, where opposite to the gap in the C-shaped portion 517, a protruding element 513 is provided, wherein the protruding armature 513 extends in a substantially perpendicular direction with respect to a plane containing the C-shaped portion 517 for a length that is greater than a thickness of the C-shaped portion 517. A screw cap boss 530 for receiving an EGT sensor 520 has an internally threaded aperture 537 to engage with a threaded part of the EGT sensor 520. The boss 530 has an abutment surface and an annular portion, with a longitudinal cavity on an internal surface which may extend from the abutment surface in an opposite direction to the internal thread 537. The diameter of the annular portion may be less than the diameter of the threaded part 537. The assembly 500 of the boss 530, the EGT sensor 520 and the rotation preventing element 510 allows for the anti-rotation element 510 to protrude into the cavity of the annular portion.
