A coupler device is for connecting first and second casings to form a casing assembly with a central axis, each casing having an inner end disposed against the inner end of the other casing such that the casings are spaced along the axis. The coupler device includes at least one generally arcuate connector having a first portion engageable with the first casing and a second portion engageable with the second casing so as to connect the two casings, the connector extending at least partially circumferentially about the casing axis. A retainer is disposeable either generally within or generally about the at least one connector and is configured to prevent radial displacement of the connector with respect to the axis so as to maintain engagement of the connector with the first and second casings.

1. An apparatus for coupling together first and second casings, comprising: a connector disposed at least partially outside of the first and second casings, the connector being at least partially arcuate in shape, the connector including an inside circumferential surface, the connector defining a first aperture and a second aperture extending radially therethrough, and the connector having first and second lugs extending from the inside circumferential surface, the first lug having a first angled drive surface and the second lug having a second angled drive surface, the first lug being configured to be received into a first recess defined in an outer surface of the first casing and the second lug being configured to be received in a second recess defined in an outer surface of the second casing,the first recess having a first angled contact surface and the second recess having a second angled contact surface, the first and second angled contact surfaces facing away from each other, the first angled drive surface being configured to slide against the first angled contact surface and the second angled drive surface being configured to slide against the second angled contact surface, andthe first aperture positioned to align with a blind hole defined in the first casing and the second aperture positioned to align with a blind hole defined in the second casing; anda retainer disposed at least partially outside of the connector and including a first threaded rod and a second threaded rod, the first threaded rod extending through the first aperture and into the blind hole of the first casing and the second threaded rod extending through the second aperture and into the blind hole of the second casing, andthe retainer being configured to force the connector inward such that the sliding engagement between the first angled drive surface and first angled contact surface and between the second angled drive surface and the second angled contact surface pushes the first and second casings together. 2. The apparatus of claim 1, wherein the first and second lugs are integral with a remainder of the connector. 3. The apparatus of claim 1, wherein the first lug is disposed proximal a first axial end of the connector and the second lug is disposed proximal a second axial end of the connector. 4. The apparatus of claim 1, further comprising a plurality of the connectors. 5. The apparatus of claim 4, wherein the plurality of connectors are positioned circumferentially-adjacent to one another. 6. The apparatus of claim 1, wherein the retainer further includes a first nut configured to engage with the first threaded rod and a second nut configured to engage with the second threaded rod, and wherein rotating the first nut and the second nut connects the first casing and the second casing together. 7. A casing assembly, comprising: a first casing having an outer surface having a first recess defined therein, the first recess extending radially-inward and having a first angled contact surface;a second casing having an outer surface having a second recess defined therein, the second recess extending radially-inward and having a second angled contact surface, the first and second angled contact surfaces facing away from each other;a connector disposed at least partially outside of the first and second casings, the connector defining a first aperture and a second aperture extending radially therethrough,the connector having a first lug configured to be disposed in the first recess and a second lug configured to be disposed in the second recess, the first lug having a first angled drive surface configured to engage the first angled contact surface of the first recess and the second lug having a second angled drive surface configured to engage the second angled drive surface, andthe first aperture positioned to align with a blind hole defined in the first casing and the second aperture positioned to align with a blind hole defined in the second casing; anda retainer disposed radially outside of the connector and including a first threaded rod and a second threaded rod, the first threaded rod extending through the first aperture and into the blind hole of the first casing and the second threaded rod extending through the second aperture and into the blind hole of the second casing, andthe retainer being configured to apply a force having a radially-inward component on the connector to slide the first and second angled drive surfaces against the first and second angled contact surfaces, respectively, to draw the first and second casings together. 8. The casing assembly of claim 7 wherein the first lug is disposed proximal a first axial end of the connector and the second lug is disposed proximal a second end of the connector. 9. The casing assembly of claim 8, wherein the first and second lugs are integral with a remainder of the connector. 10. The casing assembly of claim 7, wherein the retainer further includes a first nut configured to engage with the first threaded rod and a second nut configured to engage with the second threaded rod, and wherein rotating the first nut and the second nut slides the first angled drive surface and the second angled drive surface against the first angled contact surface and the second angled contact surface, respectively, to draw the first casing and the second casing together. 11. An apparatus for coupling together first and second casings, comprising: a plurality of connectors disposed at least partially outside of the first and second casings and axially adjacent to each other, each connector of the plurality of connectors being arcuate in shape and defining a first aperture and a second aperture extending radially therethrough, each connector of the plurality of connectors including: first and second axial ends;an inside circumferential surface extending between the first and second axial ends; andfirst and second lugs extending from the inside circumferential surface and being integral therewith, the first lug having a first angled drive surface and the second lug having a second angled drive surface, the first lug configured to be received into a first recess defined in an outer surface of the first casing and the second lug configured to be received in a second recess defined in an outer surface of the second casing,the first recess having a first angled contact surface and the second recess having a second angled contact surface, the first and second angled contact surfaces facing away from each other, the first angled drive surface being configured to slide against the first angled contact surface and the second angled drive surface being configured to slide against the second angled contact surface, andthe first aperture positioned to align with a blind hole defined in the first casing and the second aperture positioned to align with a blind hole defined in the second casing; anda retainer disposed radially outside of the plurality of connectors, the retainer comprising a first threaded rod and a second threaded rod, the first threaded rod extending through the first aperture and into the blind hole of the first casing and the second threaded rod extending through the second aperture and into the blind hole of the second casing, andthe retainer being configured to apply a force having a radially-inward component on the connector to slide the first angled drive surface and the second angled drive surface against the first angled contact surface and the second angled contact surface, respectively, to push the first casing and the second casing together.
