According to one aspect of the present invention there is provided an adjustable connector including at least two parts, each having a main body with a bore having a longitudinal axis therein, wherein an external surface of the main body of a first part is configured to bear against an internal surface of the bore of a second part when the first part is at least partially inserted into the bore of the second part to form a connection, characterized in that the positioning of the bores with respect to the main bodies is such that when the parts are connected to each other, rotation of one part with respect to the other changes the inclination of the longitudinal axes of the bores with respect to one another.

1. A golf club having a coupled head and shaft comprising: a connection mechanism to couple the head to the shaft, said connection mechanism including: a first part and a second part,the first part having a body that defines a first internal bore, wherein the first part engages a hosel of the head and rotates with respect to the hosel between a first plurality of rotational positions, wherein each of the first plurality of rotational positions is respectively identified by a different one of a first plurality of markings; andthe second part coupled to the shaft at a distal end of the shaft and configured to be inserted into the first internal bore, wherein the second part is rotatable with respect to the first part between a second plurality of rotational positions, wherein each of the second plurality of rotational positions is respectively identified by a different one of a second plurality of markings, said second part having a second internal bore, wherein the second internal bore is inclined with respect to the first internal bore and receives said distal end of the shaft,wherein aligning a first marking selected from the first plurality of markings and a second marking selected from the second plurality of markings with an indicia provided on at least one of the head and the shaft disposes the head at an orientation that is defined by a loft angle and a lie angle of the head relative to the shaft;wherein rotating the first part, while maintaining the second marking in alignment with the indicia, alters at least one of the loft angle and the lie angle of the head relative to the shaft;wherein rotating the second part, while maintaining the first marking in alignment with the indicia, alters at least one of the loft angle and the lie angle of the head relative to the shaft;wherein the first part includes a spline, key detail, or ridge to inhibit relative rotation of the second part relative to the first part when the second part is fully inserted into the first internal bore; andwherein the first part and the second part are slidably engaged to provide for rotational adjustment of the second part relative to the first part. 2. The golf club of claim 1, wherein at least one of the first plurality of markings and the second plurality of markings includes a sequence of numbers. 3. The golf club of claim 1, wherein at least one of the first plurality of markings and the second plurality of markings includes a sequence of letters. 4. The golf club of claim 1, wherein the first plurality of rotational positions includes four discrete rotational positions. 5. The golf club of claim 4, wherein the second plurality of rotational positions includes four discrete rotational positions. 6. The golf club of claim 5, wherein the first plurality of rotational positions combined with the second plurality of rotational positions provide exactly sixteen different combinations of the loft angle and the lie angle. 7. A golf club having a coupled golf club head and shaft comprising: a connection mechanism to couple the golf club head to the shaft, the connection mechanism including: a first part and a second part;the first part rotatable with respect to the golf club head between a first plurality of rotational positions, wherein each of the first plurality of rotational positions is respectively identified by a different one of a first plurality of markings; andthe second part rotatable with respect to the first part between a second plurality of rotational positions, wherein each of the second plurality of rotational positions is respectively identified by a different one of a second plurality of markings;the parts having cooperating surfaces such that aligning a first marking selected from the first plurality of markings and a second marking selected from the second plurality of markings with an indicia provided on at least one of the head and the shaft disposes the head at an orientation that is defined by a loft angle and a lie angle of the head relative to the shaft;wherein rotating the first part, while maintaining the second marking in alignment with the indicia, alters at least one of the loft angle and the lie angle of the head relative to the shaft;wherein rotating the second part, while maintaining the first marking in alignment with the indicia, alters at least one of the loft angle and the lie angle of the head relative to the shaft;wherein the first part includes a spline, key detail, or ridge to inhibit relative rotation of the second part relative to the first part when the second part is fully inserted into the first internal bore; andwherein the first part and the second part are slidably engaged to provide for rotational adjustment of the second part relative to the first part. 8. The golf club of claim 7, wherein the first plurality of rotational positions includes four discrete rotational positions. 9. The golf club of claim 8, wherein the second plurality of rotational positions includes four discrete rotational positions. 10. The golf club of claim 9, wherein the first plurality of rotational positions combined with the second plurality of rotational positions provide exactly sixteen different combinations of the loft angle and the lie angle.
