We claim: 1. A golf club, comprising: a club head including a hosel and at least one hosel alignment feature, wherein the hosel defines a sleeve bore and the hosel alignment feature is a notch that extends through at least a portion of sidewall of the hosel adjacent a proximal end of the hosel; an
We claim: 1. A golf club, comprising: a club head including a hosel and at least one hosel alignment feature, wherein the hosel defines a sleeve bore and the hosel alignment feature is a notch that extends through at least a portion of sidewall of the hosel adjacent a proximal end of the hosel; an elongate shaft; a shaft sleeve coupled to a distal end portion of the shaft, the shaft sleeve including a sleeve body and at least one sleeve alignment feature that extends laterally outward beyond an outer surface of the sleeve body and is shaped to complement the shape of the hosel alignment feature, wherein at least a portion of the shaft sleeve is received within the sleeve bore and the sleeve alignment feature engages the hosel alignment feature; a fastener that releasably couples the shaft sleeve to the club head; and at least one indicium, wherein the hosel alignment feature is a plurality of notches and the sleeve alignment feature is a plurality of tangs, and the at least one indicium is disposed on at least one of the plurality of tangs. 2. The golf club of claim 1, wherein at least one of the tangs includes tapered side edges that forcibly abut tapered side walls of at least one of the notches. 3. The golf club of claim 2, wherein said at least one of the tangs and said at least one of the notches are trapezoidal in shape. 4. The golf club of claim 1, wherein the fastener extends through the club head and threadably engages the shaft sleeve. 5. The golf club of claim 1, wherein at least one of the tangs includes curved side edges that forcibly abut curved side walls of at least one of the notches. 6. The golf club of claim 1, wherein the shaft sleeve includes a ferrule that is integral with the sleeve body. 7. The golf club of claim 1, wherein the shaft sleeve includes a ferrule wherein the ferrule and the sleeve body arc separate components and at least one of the tangs is integral with the ferrule. 8. The golf club of claim 7, wherein the sleeve body includes at least one of the sleeve notches that receives a portion of the at least one of the tangs. 9. The golf club of claim 1, wherein the shaft sleeve includes a ferrule wherein the ferrule and the sleeve body are separate components and at least one of the tangs is integral with the sleeve body. 10. The golf club of claim 1, further comprising a ferrule, wherein the fastener is integral with the ferrule and includes a threaded surface that engages a threaded surface disposed on the hosel. 11. The golf club of claim 1, wherein the hosel alignment feature is a pair of notches and the notches are disposed at diametrically opposite locations about the circumference of the hosel and aligned along an axis that is generally normal to a plane defined by a face of the club head. 12. The golf club of claim 1, wherein at least one of the notches extends through the entire sidewall of the hosel. 13. The golf club of claim 1, wherein golf club is adjustable for overall length. 14. A golf club, comprising: a club head including a hosel and a plurality of tapered notches that extend through at least a portion of a sidewall of the hosel adjacent a proximal end of the hosel, wherein the hosel defines a sleeve bore; an elongate shaft; a shaft sleeve coupled to a distal end portion of the shaft, the shaft sleeve including a sleeve body and a plurality of tapered tangs that extend laterally outward beyond an outer surface of the sleeve body, wherein at least a portion of the shaft sleeve is received within the sleeve bore and the tangs engage the notches; a fastener that releasably couples the shaft sleeve to the club head; and at least one indicium disposed on at least one of the plurality of tangs. 15. The golf club of claim 14, wherein the tangs and notches are trapezoidal in shape. 16. The golf club of claim 14, wherein the fastener extends through the club head and engages the shaft sleeve. 17. The golf club of claim 14, further comprising a ferrule, wherein the fastener is integral with the ferrule and includes a threaded surface that engages a threaded surface disposed on the hosel. 18. The golf club of claim 14, wherein the plurality of notches is a pair of notches and the notches are disposed at diametrically opposite locations about the circumference of the hosel along an axis that is generally normal to a plane defined by a face of the club head. 19. The golf club of claim 14, wherein the shaft sleeve is coupled to the shaft so that the longitudinal axis of the sleeve bore is rotated relative to the longitudinal axis of the shaft. 20. The golf club of claim 19, wherein the locations of the plurality of notches and tangs and the direction of rotation of the longitudinal axes of the sleeve bore and the shaft are selected so that shaft sleeve is rotatable between a first orientation corresponding to a first configuration of the golf club and a second orientation corresponding to a second configuration of the golf club. 21. The golf club of claim 20, wherein the first configuration corresponds to an angular attribute of the club having a first value and the second configuration corresponds to the angular attribute of the club having a second value. 22. The golf club of claim 21, wherein the angular attribute is one of face angle, lie and loft. 23. A golf club, comprising: a club head including a hosel and a plurality of notches that extend through at least a portion of a sidewall of the hosel adjacent a proximal end of the hosel, wherein the hosel defines a sleeve bore; an elongate shaft; a shall sleeve coupled to a distal end portion of the shaft, the shaft sleeve including a sleeve body and a plurality of tangs that extend laterally outward beyond an outer surface of the sleeve body, wherein at least a portion of the shaft sleeve is received within the sleeve bore and the tangs engage the notches; a fastener that releasably couples the shaft sleeve to the club head; and at least one indicium disposed on at least one tang, wherein the notches and tangs are located so that at least one tang is visible from a line of sight generally normal to a face of the club head and no tang is visible along the line of sight of a user when the club is in the address position, and wherein the indicium is at least one of a letter, a number and a symbol.
