I still think DBL is responsive and doesn't suggest pd to pass. But Mikeh convinced me that 4♦ is better.

Few claim that this DBL is penalty.
But Bridge logic suggests at least that the higher the level the more frequent a responsive DBL should be left in, not least because alternatives may look unappealing if you have to climb even higher.
Your responsive DBL at least suggests you have a positive score (otherwise you would pass or sacrifice), but you yourself are uncertain whether to bid on or not.
A responsive DBL over 3♠ (or higher) puts partner under a lot of pressure, while relieving pressure from opponents. They can pass and wait.
Partner knows you had no bid over 1♣. Now you claim you still have no clear preference, but you have values. What is partner supposed to do with a doubleton in spades?
He will often pass because there is no safety in bidding on.
In essence total trump consideration should play a prominent role here. If I had a club less and a spade more I would DBL and if partner left it in I hope he would lead a trump.
No guarantee that 3♠ can be beaten but offensive potential is poor unless partner has much more than promised so far.

Wait, partner showed diamonds and hearts with his double. I always thought that a responsive double ask partner to choose the better of at least two suits he showed with his double. (Definition f.e. here: http://www.bridgeguy...siveDouble.html
So, how can this double be responsive? Should he really choose hearts over diamonds if his hearts are better?
But I agree that "penalty double" is no good describtion either. Convertable values is the right expression, Isn't it?

Depends how you play it. Some of us expect pard to remove most of the time, whilst some expect him to leave it in with a normal hand.

Nobody said partner needs to have equal length, and with a responsive Dbl we even suggest ♣.

This is true. I would expect my partner to remove to the appropriate level of diamonds most of the time, to hearts if she happened to have five of them, and to defend 3SX only with 4=4=4=1.

I think partner's double should imply length in three suits, not two.

However, it appear that our methods are that the double showed the red suits. Given that, and given that RHO's 3♠ shows an unbalanced hand with clubs, 4♣ seems a stand-out: wants to bid, doesn't want to defend, doesn't know which suit to play in.
