Abstract: A method for connecting at least a first component (2) and a second component (3) together, wherein each component (2, 3) comprises at least one key arrangement extending along the component (2, 3) and keys (5, 6) of the key arrangement are spaced apart from one another. The method comprises the steps of: aligning the key arrangements of the components (2, 3) such that aligned keys (5, 6) of the key arrangements extend generally in line with a common axis (15) or ensuring alignment of the key arrangements such that aligned keys (5, 6) of the key arrangements extend generally in line with a common axis (15); and extending a key connector (4) comprising at least one longitudinal keyway passage (8) over the aligned keys (5, 6) generally in line with the common axis (15) so that the keys (5, 6) extend within the keyway passage (8), are retained by the key connector (4), and the first and second components (2, 3) are clamped together to form an assembly (1).
