A method for rotationally coupling a first member ( 12 ) and a second member ( 14 ). In a first step, a first member ( 12 ) and a second member ( 14 ) are provided with one of the first member ( 12 ) and the second member ( 14 ) including a portion having cutting edge(s) extending therealong. The second member ( 14 ) defines an orifice ( 14 a) for receiving therein at least a portion ( 12 a) of the first member ( 12 ). The orifice ( 14 a) is configured relative to the first member ( 12 ) such that, as the portion ( 12 a) of the first member ( 12 ) is inserted into in the orifice ( 14 a), the cutting edges on one of the first member ( 12 ) and the second member ( 14 ) engage a surface on the other one of the first member ( 12 ) and the second member ( 14 ) in a single-pass broaching operation to shave a layer of material from the surface such that the surface acquires a shape substantially conforming to a shape of the cutting edges, thereby providing tight-fitting abutting contact between the surface and the portion incorporating the cutting edges. The portion of the first member ( 12 ) is then inserted into the orifice ( 14 a) to perform the broaching operation to generate the abutting contact between the surface and the portion incorporating the cutting edges.
