- a body having a first portion and a second portion, the first portion to interchangeably couple a first golf club head with a shaft, the first golf club head being associated with a right-handed golf club;
- and
- the second portion to interchangeably couple a second golf club head with the shaft, the second golf club head being associated with a left-handed golf club;
- wherein the first portion is incompatible to couple the second golf club head to the shaft, and the portion is incompatible to couple the first golf club head to the shaft.

An apparatus comprising:
- a body having a surface, a first end, and a second end;
- a first plurality of ridges on the surface of the body at or proximate to the first end to interchangeably connect a first golf club head with a shaft, the first golf club head having a first club face characteristic;
- and
- a second plurality of ridges on the surface of the body at or proximate to the second end to interchangeably connect a second golf club head with the shaft, the second golf club head having a second club face characteristic,
- wherein the first and second club face characteristics are opposite of each other;
- and
- wherein the first plurality of ridges cannot secure the second golf club head to the shaft, and the second plurality of ridges cannot secure the first golf club head to the shaft.

- a body having a first end and a second end, the body tapers from the first end to the second end;
- a non-threaded bore at the first end to interchangeably couple the body to a portion of a shaft;
- a first male threaded portion at or proximate to the first end to interchangeably mate a first female threaded portion, the first female threaded portion being associated with a first golf club head having a first characteristic;
- a second male threaded portion at or proximate to the second end to interchangeably mate with a second female threaded portion, the second female threaded portion being associated with a second golf club head having a second characteristic;
