1. A golf club comprising:
an iron-type club head comprising:
a lie angle;
a loft angle; and
a hosel;
and
a golf coupling mechanism configured to be inserted into the hosel and configured to couple a golf club shaft with the iron-type club head;
wherein:
the hosel comprises a hosel bore configured to receive the golf coupling mechanism;
the hosel bore comprises a hosel bore axis extending along a centerline of the hosel bore;
the golf coupling mechanism comprises:
a shaft sleeve having a sleeve bore configured to receive an end of the shaft; the shaft sleeve comprising:
a top section;
a bottom section;
a sleeve axis extending along a centerline of the sleeve bore;
a sleeve coupler set having a plurality of sleeve couplers protruding from an outer surface of the shaft sleeve; the coupler set comprising:
 a first coupler having an arcuate surface curved throughout the first coupler;
 a second coupler having an arcuate surface curved throughout the second coupler;
 a third coupler having an arcuate surface curved throughout the third coupler; and
 a fourth coupler having an arcuate surface curved throughout the fourth coupler;
a shaft cap configured to be inserted into the sleeve bore;
a removable spacer configured to couple with the top section of the shaft sleeve, and a removable extender configured to couple with the bottom section of the shaft sleeve; and
an indicator system to indicate the lie angle of the club head;
the indicator system comprising:
a plurality of sleeve indicators disposed on the outer surface of the shaft sleeve;
a plurality of hosel indicators disposed on the hosel;
a viewing window; the viewing window comprising:
 a topmost end and a bottommost end;
the sleeve axis is angled with respect to the hosel bore axis such that the sleeve bore is non-concentric with the hosel bore; and
the golf coupling mechanism is configured to be rotated within the hosel to change the loft angle and the lie angle of the iron-type club head.
