The method for making a precision coupling between a pump shaft and a hollow member comprises the steps of prearranging a hollow member (10, 100) comprising a substantially cylindrical central cavity (2) and intended to be coupled with a substantially cylindrical pump shaft (20). At its central cavity (2) a ribbed profile (11, 110, 111) is made comprising a plurality of protrusions (12) comprising a determined number of centering protrusions (12a) and a remaining number of transmission protrusions (12b). |
