Claim 8:
9. A rotatable component for keyed coupling with another component, the rotatable component having a rotation axis and comprising:
a keyseat having a keyseat opening for receiving a key therein, the keyseat including:
a pocket including a concave floor engageable with a part of the key, the floor having a curved axial cross-sectional profile relative to the rotation axis of the rotatable component;
a first keyseat extension extending in a first axial direction from the pocket relative to the rotation axis of the rotatable component; and
a second keyseat extension extending in a second axial direction opposite the first axial direction from the pocket relative to the rotation axis of the rotatable component,

wherein:
the pocket has a maximum pocket depth relative to the keyseat opening;
a maximum depth of the first keyseat extension relative to the keyseat opening is less than the maximum pocket depth; and
the maximum depth of the first keyseat extension is between 0.5 times the maximum pocket depth and 0.8 times the maximum pocket depth.
