Abstract

In a golf club, an apparatus which provides for a shaft to be adjustably secured to a head comprises a skewed axis shaft coupling and a shaft having an intermediate shaft section which joins a nominal shaft section to an offset shaft section such that they are offset one from the other. A shaft indexing mechanism provides for the nominal shaft section to have a plurality of indexed rotational positions in a socket of the skewed axis shaft coupling, thereby providing for the head to have, with respect to the offset shaft section, a plurality of possible sets of spatial and mass distribution properties. Furthermore, the skewed axis shaft coupling provides for the head to have, with respect to the nominal shaft section, a plurality of sets of angular properties.
