A handle shaft assembly includes a tube spacer, a handle shaft, a stuff box, and an operational handle. The stuff box may be configured for insertion into a through-hole within a bottom loading coupler body and include first and second stuff box ends defining a cylindrical cavity. A first sealing member may be positioned on the first stuff box end, and a second sealing member positioned on the second stuff box end. The tube spacer may be configured to be positioned within a blind counterbore of the bottom loading coupler body. The handle shaft may include a first end positioned within the tube spacer configured to be positioned with a blind bore of the bottom loading coupler body, a linkage section configured to be coupled to a drive linkage of a poppet valve assembly, and a second end extending through the cylindrical cavity of the stuff box. The operational handle is mechanically coupled to the second end of the handle shaft.

The handle shaft assembly of claim 2 wherein the flange portion of the stuff box is hexagonally shaped. 5. The handle shaft assembly of claim 2 wherein the flange portion of the stuff box is configured to rest on an outer surface of the through-hole. 6. The handle shaft assembly of claim 1 wherein: the handle shaft further comprises a cylindrical portion adjacent to the linkage section;the cylindrical portion comprises a diameter that is greater than a thickness of the linkage section; anda first end of the cylindrical portion is configured to be positioned against a first surface of the drive linkage. 7. The handle shaft assembly of claim 6 wherein the cylindrical portion comprises a collar located at a second end, and the collar is configured to provide an abutment surface for the second end of the stuff box. 8. The handle shaft assembly of claim 1 wherein the tube spacer comprises a cylindrical shape having a second end that is configured to be positioned against a second surface of the drive linkage. 9. The handle shaft assembly of claim 1 wherein: the handle shaft further comprises a cylindrical portion adjacent to the linkage section, the cylindrical portion having a diameter that is greater than a thickness of the linkage section;the tube spacer comprises a cylindrical shape having a second end; anda first end of the cylindrical portion is configured to be positioned against a first surface of the drive linkage, and the second end of the tube spacer is configured to be positioned against a second surface of the drive linkage such that lateral movement of the drive linkage along the handle shaft is substantially prevented upon insertion of the handle shaft into the drive linkage and the tube spacer. 10. The handle shaft assembly of claim 1 wherein the handle shaft is substantially free from rotation with respect to the drive linkage when the linkage section of the handle shaft is positioned within a drive linkage slot of the drive linkage. 11. The handle shaft assembly of claim 1 wherein the linkage section and a drive linkage slot of the drive linkage have a cross sectional geometry that substantially prevents the handle shaft from rotating within the drive linkage when the linkage section of the handle shaft is positioned within the drive linkage slot. 12. The handle shaft assembly of claim 11 wherein the cross sectional geometry comprises first and second opposing planar surfaces. 13. A handle shaft assembly for use in a bottom loading coupler, the handle shaft assembly comprising a tube spacer, a handle shaft and a stuff box, wherein: the stuff box comprises: first and second stuff box ends defining a cylindrical cavity therebetween;a flange portion at the first end defining a first seat having a first sealing member positioned therein;an annular groove located at the second end, the annular groove having a second sealing member positioned therein; anda threaded portion at the first end configured to mate with a corresponding threaded portion of a through-hole within a bottom loading coupler body;a first end of the tube spacer is configured to be positioned within a blind counterbore of the bottom loading coupler body and the first end of the handle shaft is configured to be positioned within a blind bore of the coupler body that extends from the blind counterbore of bottom loading coupler body, wherein the blind counterbore and the blind bore are positioned outside of an inner cylindrical cavity of the bottom loading coupler body; andthe handle shaft is configured to be coupled to a poppet valve assembly and comprises a first end positioned within the tube spacer and a second end that extends through the cylindrical cavity of the stuff box. 14.
