Abstract
A method and apparatus for joining first and second bodies coaxially together to resist relative axial and rotational movement between the bodies. A male portion of the first body is received in a complementary female portion of the second body, and the male and female portions are aligned axially on a common axis such that respective cooperating grooves in opposing cylindrical or tapered complementary surfaces of the male and female portions are aligned to form a plurality of passageways or a passageway having a plurality of passageway portions, between the opposing cylindrical or tapered complementary surfaces. At least two of the passageways or at least two of the passageway portions are disposed at different angles to the common axis. Solid mechanical coupling elements are loaded into each passageway or into the passageway having the plurality of passageway portions, such that each passageway or the passageway having the plurality of passageway portions is substantially full of the solid mechanical coupling elements.
