Nuclear artillery shells are intended as last ditch weapons when you are in a situation where sacrificing your own troops, civilians or tracts of land (anything bombed will be largely be unuseable for a good while) is a thinkable strategy. In other words, it is for use on your own territory.
Nuclear torpedos are either intended as "land torpedoes" (the Soviet T-15, where you basically substitute the missile or long range bomber for a submarine), or as anti-submarine torpedoes (the ASTOR) to use on nuclear subs that you would otherwise have no chance of taking out. The first is just a marine version of a Hiroshima-type bomb, the other is a first strike weapon, to stop the enemy submarine from raining death on your own country. Neither are very practical, you are likely to loose whatever vessel is launching it.
There has been some movement to try to produce small, "tactical" nuclear warheads. Bush was arguing for a nuclear "bunker-buster". So far, the technical problem is to make nuclear weapons small enough to not be an city size destruction area weapon. That nuclear artillery shells and torpedoes exist does not mean they are a good idea. Cold war deterrent logic can make anyones head spin.
