Golf club heads with golf coupling mechanisms

A golf coupling mechanism for joining golf club heads and shafts allows for adjustment of a club head loft angle, a club head lie angle, and a club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve 156, a removable spacer 216 and a removable extender 228, wherein a fastening assembly secures the coupling mechanism to the club head. In a contracted configuration, the mechanism includes the shaft sleeve. The mechanism further includes a shaft cap 192 to soften the interaction between the shaft and the golf coupling mechanism. The mechanism further comprises one or more arcuate coupler sets 184 to frictionally lock the shaft relative to the golf club head. The extender may comprise a threaded post which engages with the shaft sleeve (fig.15).
