The invention claimed is: 1. A fuel cell assembly for a fastener-driving tool, comprising: a fuel cell having a closure formation; an adapter including a ring portion configured for engagement upon said fuel cell closure formation and including a top edge, a bottom edge and a sidewall therebetween
The invention claimed is: 1. A fuel cell assembly for a fastener-driving tool, comprising: a fuel cell having a closure formation; an adapter including a ring portion configured for engagement upon said fuel cell closure formation and including a top edge, a bottom edge and a sidewall therebetween having an inner sidewall and an outer sidewall, said inner sidewall defining at least one track extending from said top edge to said bottom edge, and said outer sidewall having a convex gripping formation complementary to said closure formation; and a cap or metering valve constructed and arranged for being removably secured to said adapter and including a leg portion having a foot constructed and arranged for being received in said undercut portion. 2. The fuel cell assembly of claim 1 wherein said fuel cell is one of an in-can fuel cell and an on-can fuel cell. 3. The fuel cell assembly of claim 1 wherein said cap is one of an in-can cap and an on-can fuel metering valve. 4. The fuel cell assembly of claim 1 wherein said adapter further includes at least one notch, each notch defined in said inner sidewall adjacent to a corresponding one of said tracks and configured for receiving a corresponding foot for securing the adapter in a shipping position. 5. A fuel cell assembly for a fastener-driving tool, comprising: one of an in-can fuel cell and an on-can fuel cell, each of said fuel cells having a closure formation; an adapter including a ring portion configured for engagement upon said fuel cell closure formation and including a top edge defining at least one indentation, a bottom edge defining at least one gap in vertical alignment with said indentation, and a sidewall therebetween having an inner sidewall and an outer sidewall, said inner sidewall defining at least one track extending from said top edge to said bottom edge, and said outer sidewall having a convex gripping formation complementary to said closure formation; and a cap constructed and arranged for being removably secured to said adapter and including at least one leg portion each having a foot constructed and arranged for being received in said track and a detent radially extending from said foot and configured for being received in said gap upon rotation of said cap relative to said adapter. 6. The fuel cell assembly of claim 5 wherein said cap is one of an in-can cap and an on-can fuel metering valve. 7. The fuel cell assembly of claim 5 wherein said at least one track is a pair of tracks, each track beginning at opposite sides of said top edge and extending in opposite directions to said bottom edge in a helical formation, said gap defining an end of said track. 8. An adapter configured for use in combination with a cap or metering valve on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, comprising: a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall; a grooved portion defined by said inner sidewall, wherein said grooved portion is an arcuate undercut portion defined by said inner sidewall and adjacent to said bottom edge; a convex gripping formation on said outer sidewall complementary to the closure formation; and at least one recessed formation adjacent said grooved portion for receiving the foot. 9. The adapter of claim 8 further including a stop defining an end of said arcuate undercut portion, said stop being constructed and arranged for preventing rotation of the cap or metering valve foot past said stop. 10. The adapter of claim 9 wherein said undercut further includes at least one radially outwardly extending nodule spaced from said stop to define a space for receiving the foot upon completion of installation. 11. An adapter configured for use in combination with a cap or metering valve on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, comprising: a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall; a grooved portion defined by said inner sidewall, wherein said grooved portion is at least one track defined in said inner sidewall and extending from said top edge to said bottom edge; a convex gripping formation on said outer sidewall complementary to the closure formation; and at least one recessed formation adjacent said grooved portion for receiving the foot. 12. The adapter of claim 11 wherein said at least one track is a pair of tracks, each track beginning at opposite sides of said top edge and extending in the same rotational direction to said bottom edge in a helical formation. 13. The adapter of claim 11 wherein said ring portion further includes at least one seat defined in said inner sidewall adjacent to said top edge, each said seat defining a beginning of each said track. 14. The adapter of claim 13 further including at least one notch, each notch defined in said inner sidewall adjacent to a corresponding one of said seats and configured for receiving a corresponding foot for securing the adapter in a shipping position. 15. An adapter configured for use in combination with a cap or metering valve on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, comprising: a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall, wherein said top edge defines at least one indentation constructed and arranged for receiving a corresponding projection of the cap or metering valve for properly aligning and securing the cap to the adapter, said projection being in vertical alignment with the cap or metering valve leg; a grooved portion defined by said inner sidewall; a convex gripping formation on said outer sidewall complementary to the closure formation; and at least one recessed formation adjacent said grooved portion for receiving the foot. 16. The adapter of claim 15 wherein each said indentation defines a generally centrally located slot constructed and arranged for receiving a corresponding protrusion depending from said cap projection, for securely engaging the cap with the adapter. 17. An adapter configured for use in combination with a cap or metering valve on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, comprising: a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall; a grooved portion defined by said inner sidewall; a convex gripping formation on said outer sidewall complementary to the closure formation; and at least one recessed formation adjacent said grooved portion for receiving the foot, wherein said recessed formation is a gap defined between opposing ends of said ring portion. 18. The adapter of claim 17 wherein the cap further includes a detent radially extending from the foot, said detent constructed and arranged for being received in said gap, securing the cap to the adapter.
