21. A method of assembling a housing assembly for a downhole tool, the method including:
arranging a tool body, carrying a payload, within a bore defined by a coupling adaptor, the tool body having a longitudinal axis and defining a plurality of coupling channels, each coupling channel dimensioned to receive one of a plurality of protrusions defined by the coupling adaptor and extending radially into the bore, and each coupling channel defining a pair of axial channel portions extending parallel to the axis and spaced apart about the axis, and a joining channel portion extending circumferentially about the axis to join between the axial channel portions, such that arranging the tool body within the bore causes at least one of the plurality of protrusions extending from the coupling adaptor to insert into a complementary at least one coupling channel defined by the tool body;
axially displacing the tool body relative to the adaptor to slide the at least one protrusion along one of the pair of axial channel portions;
rotating the tool body relative to the adaptor to slide the at least one protrusion along the joining channel portion; and
axially displacing the tool body relative to the adaptor to slide the at least one protrusion along the other one of the pair of axial channel portions to cause the tool body to be mounted to the coupling adaptor.
