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.

Disclosed are systems and methods of adjusting the playing orientation of the head of a golf club. An adjustment to the axis of the shaft in reference to the vertical plane is constrained within minimum and maximum limits, so as to conform to current and proposed changes to the United States Golf Association (USGA) rules of play. The fine adjustment within these constraints cannot be readily made, and all adjustable parts are firmly fixed, so there is no reasonable likelihood of them working loose during a round. The adjustments to the club are designed such that during a stipulated round, the playing characteristics of a club cannot be purposely changed by adjustment or by other means.

A universal connector for an adjustable golf club is provided. Such a universal connector includes a first member having a head portion and a body portion and having a bore for receiving a terminal end of a shaft. The connector also includes a second member having a bore for receiving a portion of the first member therein. The first member includes a first anti-rotational member and the second member includes a second anti-rotational member. The first and second anti-rotational members are engageable with one another to prevent relative rotation of the first member relative to the second member about a longitudinal axis of the connector. The second member includes a third anti-rotational member, the third anti-rotational member configured to mate with an anti-rotational member of the golf club head to prevent relative rotation of the second member relative to the head.

A shaft for a golf club includes a first end, a second end, and a demarcation. The first end is adapted to attach to a club head. The second end is adapted to receive a grip distal to the first end. The demarcation is positioned at or adjacent to the balance point of the golf club between the first end and the second end.

Golf club heads include a golf club head body, a ball striking face, and a shaft engaging member configured to engage a golf club shaft with the golf club head body. The golf club head may be configured with a first piece and a second piece, which may be in the form of the shaft engaging member and a body member connected to the shaft engaging member. The shaft engaging member includes a base member and an arm extending from the base member, and the body member includes a face having a striking surface configured for striking a ball and a club head body positioned behind the face, the second piece having a receiving slot positioned behind the face, where the base member of the first piece is at least partially received within the receiving slot.
