Claim:
1. A method of joining first and second bodies coaxially together to resist relative axial and rotational movement between the bodies, the method comprising: receiving a male portion of the first body in a complementary female portion of the second body; aligning said male and female portions axially on a common axis such that respective cooperating grooves in opposing cylindrical or tapered complementary surfaces of said male and female portions are aligned to form a plurality of passageways or a passageway having a plurality of passageway portions, between said opposing cylindrical or tapered complementary surfaces, at least two of said passageways or at least two of said passageway portions being disposed at different angles to said common axis, each angle being defined between a direction of the common axis and a direction in which one of the at least two of said passageways or one of the at least two of said passageway portions extends; and loading solid mechanical coupling elements into each passageway or into said passageway having said plurality of passageway portions, such that said each passageway or said passageway having said plurality of passageway portions is substantially full of said solid mechanical coupling elements.
